Add trending section or sort order

Description of your request or bug report:

I think it would be cool to see what’s trending on the site at any given time. That is, what book or video pages are being visited a lot and/or added to lists a lot within some kind of recent time period. I’m not sure there’s a general definition for this kind of thing, so it could require some experimentation. This could be a new section on the home page or another option is to add it as a sort option on the main book and video pages.
